6 Game Of Thrones Spinoffs That Were Canceled & Rejected By HBO


6 Aegon The Conqueror

Aegon the Conqueror is a fabled figure in Game of Thrones and House of the Dragon, known as the Targaryen, who arrived from Valyria and forced the great houses of Westeros to their knees. A prequel about Aegon's conquest was written by screenwriters Rand Ravich and Far Shariat (via ). The script apparently portrayed Aegon as a drunken ruffian, something he'd never been described as in the books. The pitch was rejected, though has since revealed another attempt at the story is being worked on. An after House of the Dragon.

5 Flea Bottom

Referenced several times in Game of Thrones


as one of the lowest-income areas of King's Landing, Flea Bottom is the home of Davos Seaworth and Gendry. A series based on life in the slum was discussed at one point, though it was reported as not moving forward as of July 2021 (via ). Pitches attempted to explore several different angles of the Game of Thrones universe, though it's not entirely surprising the Flea Bottom show didn't have the traction to progress forward.

4 Nymeria

Not to be confused with Arya's direwolf or Jessica Henwick's Nymeria Sand from Game of Thrones, Princess Nymeria of Ny Sar was a Dornish warrior queen who lived centuries before


House of the Dragon and Game of Thrones. One of the various rejected pitches for a prequel series was one exploring her character from writer/producer Brian Helgeland (via ). This story could have been fascinating and redeemed the treatment of Dorne in Game of Thrones.

3 Doom Of Valyria

was a chain of volcanic eruptions that destroyed the thriving city of Valyria in Essos. Old Valyria is mentioned several times throughout Game of Thrones and House of the Dragon as the home of the Targaryen family and a city ruled by dragon riders. The fabled Valyria would've been exciting to see on screen in a story of characters unknowingly existing just before their deaths at the hands of a cataclysmic event.


The series was pitched by Kong: Skull Island's Max Borenstein (via ), though this is another area of the world's history that is perhaps best left in mystery.

2 The Seven

The Faith of the Seven is one of the that is mentioned frequently in the two series. One of the far-fetched pitches for a prequel was about the fabled Seven Gods, as if they were real people roaming the world, showing how they came to be worshiped (via ). The idea didn't make it too far and likely wouldn't have had the traction to follow up the original series.

1 Dunk And Egg (Initially Rejected)

The next Game of Thrones, which will adapt the novellas commonly called


The Tales of Dunk and Egg. The story follows the fabled Lord Commander of the Kingsguard, Ser Duncan the Tall, and King Aegon V Targaryen, also known as Egg, in their early days, adventuring around Westeros. HBO initially passed on adapting the series (via ), but it's now planned to be the third TV series in the universe, taking a less complex, light-hearted approach to the universe.
